Claims priority, application Germany December 17, 1952 1 Claim. (Cl.206-37) This invention relates to powder compacts.

It aims at obviating a serious disadvantage of ordinary powder compacts,namely the fact that the hinge holding the lid forms parts which projectfrom the edge of the box and which are not only found inconvenient whengripping the latter but also, when they have sharp edges as is often thecase, damage other articles contained in the handbag, in which thepowder compact is usually kept, and may also cause injury to the user.

According to the invention this disadvantage is avoided, that is to saythe creation of a smooth, completely round edge of the box is renderedpossible, by locating the hinge in a space in the body of the box whichis formed by removing a corresponding segment from the box spacereceiving the powder block and which in known compacts is circular.

By the use of powder blocks flattened on one side, the useful purpose ofthe compact is not in any way impaired. Such blocks can be produced inthe same manner as completely circular blocks.

As a result of the profiling of the interior space of the compactaccording to the invention, the purchaser will be compelled always tobuy the makers refill blocks or inserts which is to the advantage of theseller of powder compacts of this type. As a further development of theinvention this can be additionally ensured, within the framework of thefundamental principle of the invention, by giving predetermineddimensions to the internal profilings of the space in the body of thecompact which permit the insertion only of a predetermined, similarlyshaped refill.

A particular advantage of the invention also consists in that the powderblock is secured against turning, that is to say it cannot be caused toperform a rotational movement when, as is customary, the powder isremoved by rubbing in a circular movement.

In addition the colour indication labels, usually pro vided on the holein the bottom of the compact, will always be the right way up.

One exemplified embodiment of a powder compact according to theinvention, which is preferably made in the customary way of a syntheticplastic, is illustrated in the accompanying drawings, wherein:

Figure 1 shows a vertical section through the compact in the closedcondition,

Figure 2 shows the same construction of compact with the lid raised,

Figure 3 shows a top view of the box, and

Figure 4 shows an elevation of the box, revealing the visible parts ofthe hinge.

In the drawings a denotes the body of the compact in the interior ofwhich is situated the insert b holding the powder block. At 1: isindicated the usual central hole in the base of the compact permittingthe lifting of the insert with the powder block contained therein. Ascan be seen from the figures, the interior of the compact is flattenedalong the portion adjacent the hinge, as shown at d, and the insert b,like the powder block accommodated therein, is correspondingly shaped.

This produces at the respective point an internal thickening e at therim of the compact body a, in the form of a segment of a circle, inwhich the hinge is formed. The hinge, in itself of usual construction,consists of the hinge pin 1, which is mounted in the body a, and aroundwhich the projection g of the lid h is rotatable in a correspondingrecess i in the thickened portion e.

As will be seen from the drawings, this results in th edge of thecompact being completely devoid of projecting parts, and thus aconstruction of the powder compact by which all the abovementioneddisadvantages of the known constructions thereof are avoided.

In order to prevent leakage of the powder from the compact box when thelatter is closed, an integral upstanding flange k (Figs. 2 and 3) isprovided on the inner edge of the rim of the generally cylindricalshallow powder chamber or compact body a, whereby this otherwisecircular flange is straight at the segment-shaped portion of the rim.The lid 11 has a correspondingly shaped inner recessed part 1, which isadapted to receive the flange k, when the lid h is in closing positionon the top of the rim of the compact body a.

The invention is naturally not restricted to the embodiment described indetail above and illustrated in the drawings.

I claim:

In combination, a receptacle, said receptacle defining a cosmeticcompact and comprising a bottom and a top, said top being pivotallymovable into closed position over said bottom and being releasably heldthereover to define therewith a spill-proof compact of shallowcylindrical form having uninterrupted, cylindrical outer walls and abottom and top having smooth uninterrupted outer surfaces, at shallowcosmetic block receiving chamber provided in said bottom, said chamberbeing defined by a substantially uniform annular rim, said rim beinginterrupted to define a thickened, segmental hinge connection portionhaving a recess provided therein, a continuous upwardly disposedperipheral lip disposed on said rim, said lip conforming to theconfiguration of said chamber and including an interrupter chord-likeportion disposed between said chamber and said recess, said topincluding a shallow cylindrical recess surrounding said upwardlydisposed peripheral lip provided on said bottom rim when said top isclosed over said bottom to seal said cosmetic receiving chamber, saidtop including a downwardly projecting ear, said ear being received insaid recess provided in said bottom segmental hinge connection portion,a pin pivotally fixing said ear in said recess to define a hinge meansabout which said top may pivot relative to said bottom, a block ofcosmetic powder removably emplaced in said bottom, said block includingan interrupted periphery registerable with said rim and said interruptedportion thereof whereby said block is anchored against rotation withinsaid shallow block receiving chamber and said hinge means is recessedwithin the thickened segmental rim portion.
